Should The Minimum Drinking Age Be Raised Or Lowered? Thesis Example

It would be more efficient and safer to raise the minimum drinking age or at least make sure we do not lower it. Of course, many people object to this opinion:

List A

1. They would argue that people under twenty-one years old (at the age of eighteen or nineteen) have the right to consume alcohol under controlled conditions, like in restaurants and bars, because this could be a model for them to learn to drink responsibly in the future. (Ruth C. Engs, Professor) In my opinion, however, there will always be time for these people to become responsible when they are twenty-two years old.
2. Another argument that this group of people have is that though the legal age for drinking is twenty-one, younger people are drinking anyway, and they are doing it in an irresponsible manner, because whatever is illegal, sounds tempting to us human beings by nature. (Ruth C. Engs, Professor) Of course, this is true, but I do not think legalizing alcohol for eighteen-year-olds would make the situation any better.

List B

The drinking age should be raised or remain constant because there are lots of accidents that happen when drunk teenagers are driving. Teenagers love speed, and when speed is accompanied with being drunk, they become out of control. Unfortunately, tragic events can happen is these kinds of situations. Of course, any proponents of the “lowering the minimum age” would respond that lots of adults cause drunk-accidents too and this has nothing to do with how old drivers are.
I think it is important to think about tragedies that happen on the roads seriously. Drinking is something people do every day; if it is legalized for eighteen-year-olds, they would be drunk-driving all the time, and we cannot compare them to grown-ups who are of course more responsible and aware of the dangers.
2. Another theory that supports raising the minimum age is completely scientific. According to this theory, the human brain is not fully grown until the age twenty-five; so why should anyone start damaging their brain before it has a chance to grow up? (debate.org) An opponent would provide a scientific answer, for example they would say that alcohol does not damage your brain unless it is used in excess, and thus this could happen to anybody, even grownups.
The fact that alcohol damages the brain is more or less proven; thus any counterarguments to the statement that “drinking teenagers would be preventing their brains from growing up”, are somehow opposing science, and that is why I do not assume them correct.
